FOOD PRODUCT AND PROCESS 0F iIAKI'NGABYAME.

Application nled July 9,

To ZZ whom it may concern:

Be it known that FRANK M. ASHLEY, a citizen of the United States, and a resident of New York city7` borough of Brooklyn, in the county of Kings and State of New York, has invented certain new and useful Improvements in Food Products and Processes of Making Same, of which the following is a specification.

Myv invention relates to food products andthe object of 'my invention'is to provide a new food or rather an old food preparation in a new form, and a novel method of making'the same.

My invention'may be describedand better understood by referring to the drawing which forms a part of this specification which shows a vertical sectional view of an apparatus by means of which the new product is made and the newprocess carried out.

A, indicates a pail or receptacle provided 'with a closed cover B and a stop-cock C.

D, indicates astrong receptacle havinga cover E which is held in steam tight relation to the receptacle D by a threaded ring F, a 'gasket Gr being interposed between the 4receptacle and cover to assist in making a tight joint.

The cover may be provided with apressure gage H and-an inlet passage Ihaving a check valve J and a stopcock K.

An outlet pipe L extends from the bot tom of the cover nearlyto` the bottom of the receptacle and'through the cover to a dischar e valve M located-above the same.

A fluid N' consistingo'f cream in combination with other ingredients such forvilllustration as those used for making ice creams with their respective flavors, may

beplaced'in the receptacle D and 'compressed air or .carbonio acid gas is then introduced into the receptacle D through the passage I and the cream fluid charged with same by shaking or otherwise agitating the fluid until it is Well charged with the'gas.

. -The pail A is then filled with ice or lcold `brine such as used to freeze ice in ice making apparatus and the fluid N cooled to a1- most'the freezingpoint of the fluid in the closed receptacle D. When the valve Mv is opened the fluid is forced out by the gas in the receptacle above the fluid, and as it is discharged it is instantly frozen into a frost puff of relatively large volume due to the expansion of the gas with whichv it is charged and by reason of the said ex- 1921. Serial No. 488,473.

pansion of gas a refrigerating effect is produced causing the fluid to freeze in a volume many times greater than that of a corresponding amount of the fluid within the receptacle, thus providing a delicious product.

If it is desired to have the cream or fluid within the receptacle D keep for a considerable period of time to prevent it from becoming sour, I prefer to sterilize the fluid N before it is charged with the gas and this is carried out as follows.

Sufficient water is placed in the receptacle A so that the same will extend to a. suitable height such as up to the line A after I f By the above process the cream fluid N is' autoniatically and instantly converted from a fluid to a solid, its volume increased, and a new productprovided.

For vlarge commercial use and sale the receptacles D may be made of thinl sheet vmetal or vs trong glass, and the fluid N placed therein and treated, the receptacles being provided with ay simple discharge valve on a tube as indicated or with a valve located at the bottom of the receptacle and the receptacle delivered to the user without first cooling and thejuser can place the receptacle on ice or in a sufficiently cold refrigerator to cool it to thenecessary degree to form the frozen puff when it is discharged from the receptacle and I have found some people who prefer it served below the freezing point. In this case I cool the'uid but not to the point where it freezes when discharged from the receptacle, but to a oint where it is cold enough to form a -pu that Willj'stand firmly when discharged and in this condition it ma be served as a dessert and for covering makes an excellent dish.

The fluid may be made to -hold its form for a longer time if some gum tragacanth-A erries-pies, etc., and

and after cooling to near the freezing point isready for use as above set forth.

or Acornstarch or gelatin is added as an' inclaim as new:

1. The process of treating a fluid. comprising an ice cream mix to provide a foodv product consisting inhcharging the Huid with a suitable as under pressure in a container, cooling t e fluid nearly to its freezing point and then discharging the fluid from the container at or near its freezing point. p

2. The process of treating a fiuid comprising an ice cream mix to rovide a food roduct consisting in steri lzing the fluid 1n a container charging the uid with a suitable us under pressure, coolin the fluid near y to its freezing oint an then .discharging the iiuid from t e container at or near its freezing point.

3. A new product made from a fiuid at or near the freezing temperature thereof comprising an ice cream mix impregnated with gas, in puff form.

4. A new product made from a fiuid at or near the freezing temperature thereof comprisin cream impre ated with gas, expande in volume an solidied.

V Signed at New York in the county of New York and State of New York this 7th day of July A. D.
